No los tendrias que mandar por POST, eso le quita interactividad a tu programa (refrescar la pagina). Ademas, yo no uso asp, pero recojer un POST debe ser lo mas basico del lenguaje.
Código:
Request.Form
The Request.Form command is used to collect values in a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
If a user typed "Bill" and "Gates" in the form example above, the URL sent to the server would look like this:
http://www.w3schools.com/simpleform.asp
Assume that the ASP file "simpleform.asp" contains the following script:
<body>
Welcome
<%
response.write(request.form("fname"))
response.write(" " & request.form("lname"))
%>
</body>
The browser will display the following in the body of the document:
Welcome Bill Gates
